MSI is keen to redefine the GAMING SSD and lands in the NAND arena with a bang. The two upcoming SSDs have been designed to deliver storage up to 4TB, read speeds up to 7000 MB/s, and write speeds up to 6900 MB/s. 

Little info has been shared otherwise. The NVMe M2 SSD units are being fitted with a cooler. We expect something Phison based alright. The slide you see mentioned up-to 7000 MB/sec reads and a staggering 6900 MB/sec writes. NAND used is TLC (3-bits per cell), and MSI will offer up to 4 TB versions. More info to follow as soon as we receive it.

Update April 12th, 2021: over at an event Asia-based event, the names have been uncovered. Multiple products are coming up including two MEG Z590 Unify series motherboards and the Spatium line of high-end M.2 NVMe SSDs. The motherboard MEG Z590 UNIFY and MEG Z590 UNIFY-X focuses on extreme memory overclocking. The products are equipped with 16+2 90A DrMOS power supply, 8-layer 2OZ copper foil, server-level PCB and other highlights. And equipped with a 2.5G network card and WiFi 6E.

Back to the Spatium SSDs though. It seems that MSI is still fooling around with several heatsink designs. Re-confirmed is of course PCI-Express 4.0 x4 and capacities of up to 4 TB. NAND will be TLC-based and again transfer rates of up to 7000 MB/s read, with up to 6900 MB/s writes are listed. That screams Phisopn all over the place.
